[Bug 686627] Re: Samba server crashes on file read.
Sorry. Nothing of interest in syslog. The server is a model name : Intel(R) Core(TM)2 Duo CPU E6550 @ 2.33GHz running a Ubuntu 10.04.1 LTS 64 bits version. The clients are always Windows XP Professional SP2/3 32bits. We get the bug on the server. The smb.conf file is attached. You will find no share in this file. It is the package default one. The share is shared using the Share this folder option in nautilus.

In addition to the information requested in comment #3, please append your samba configuration files.

When this happens, do you get any kernel oops in syslog?

Hi Serge, Thank you for helping. I get this error when a file is read through samba. It happens sometimes and sometimes not. I don't know what are the circumstances that make it happen. If you want me to do further tests, I will be glad to help you. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in ubuntu. https://bugs.launchpad.net/bugs/686627 Title: Samba server crashes on file read. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
